German Language/letter writting

QuestionI just started learning German and i need to write a letter to the tourist information centre. Can you please help me check for grammatical errors(some of the words i use translator), do check for the mistakes too. I know there is a lot of mistake, your help will be very appreciated.Thanks Janina.

I will try and help you with your letter to the tourist information centre. However, I would also like to ask you to send me the letter in English, as I am afraid that I don't understand all of the things you want to say in your letter.
I'd also like to point out that you can also contact the Berlin tourist information in English as well. They have to be prepared to be contacted by people from all over the world, so they are also prepared to be contacted in English.

So, here's your letter (the parts I am not sure of I put in brackets):

Expertise

As a native German speaker working professionally with languages, I can answer questions concerning German grammar, spelling and punctuation.
I can also help with understanding and short German-English translations. As I also speak French, I might also be helpful concerning German-French translations. Translation only refers to short texts here.

Experience

I am a German native speaker working as a translator for English and French. I am concerned with language issues as grammar and spelling on a daily basis. I am very interested in these kind of topics, as any good translator should be. I also have a very good insight in the differences between English and German (and also French), so I might be able to give helpful explanations why specific things are the way they are in a specific language.

OrganizationsI am a member of the German Translator Association BDÜ.

PublicationsMy translations are published in form of manuals, company and product presentations, and websites, but you won't find my name there, as translators of technical texts are only rarely featured.

Education/CredentialsI studied translation at the University of Applied Sciences in Cologne (FH Köln), and have been working as a freelance translator for five years now.

Awards and HonorsI haven't received any awards, but receiving awards is really quite rare for translators.

Past/Present ClientsMostly translation agencies in many different countries.
